I really wanted to like this book. The cover had great promise, and the Istanbul setting seemed like it would be terrific.Sadly, it just really didn't live up to the promise of either.
I spent a lot of time bored. Probably that is what espionage really is - months and years of boredom punctuated by minutes and hours of adrenaline fueled terror. Nonetheless, verisimilitude aside, I was meh on the main character, and the setting of post-war Istanbul didn't come through for me.
There were a few others by Kanon that looked appealing, but with so many other books, and so little reading time, I may just write him off completely.
